"I bought it. But first it worked with 1 month license. Then it wont work any more during first month. its stuck or limited checking. my obd shown last 2 message. i unlpugged and plugged it to laptops and cars no any reaction just last 2 message shown. nothing happen. then i contacted support center they suggested to call to bla bla numbers. But how can i call to usa from asia. why they cant explain it via e mail. there is time zone problem. I think waste of time waste of money. If you checked it shows only code p0455 .......... it doesnot tell you more details until you connect to windows laptops. Beware!!!"posted by: User on November 2, 2013
